Φ120/Φ360 × 320mm four-roll mill rolls deformation calculation
Abstract：Plate crown and flatness is a measure of an important indicator of the quality of plate shaped, they are both independent and interact with each other, the convexity load depends mainly on the shape of the roll gap, so accurately calculate the elastic deformation of rolls, on the roll gap setting are important. Influence function method using four-roll mill rolls conducted a systematic analysis of elastic deformation, by smoothing index correction method for correcting pressure between rolls, Establish a more suitable site model, Calculated using Visual Basic language program processes, calculate the amount of flattening between work roll and back-up roll and rolling between work roll . Proceed from the rolls deformation analysis, Optimized for the back-up roll, And then reduce rolling plate differential, the role eventually reach panel shape.
Keywords: elastic deformation； Influence function； shape control； smoothness index
